Check out How to create a bookmarklet if you're interested in learning more about bookmarklets.

[jquerify]: javascript:(function()%7B%22use%20strict%22;function%20t()%7Bconsole.log(%22jQuery%20loaded!%22)%7Dvar%20e;e=document.createElement(%22script%22);e.addEventListener(%22load%22,t);e.src=%22//;document.head.appendChild(e)%7D())

If you drag this bookmarklet to your bookmarks bar and click on it on any page (with some exceptions), it will load jQuery.


  1. Use Google Chrome
  2. Click on the menu button in the upper-right-hand corner (looks like 3 vertical bars stacked on top of eachother)
  3. Move your mouse over Bookmarks
  4. Select Show Bookmarks Bar if it isn't already selected
  5. Click and drag the jQuerify link (above) to the Bookmarks Bar
  6. On any page, click the link and jQuery will load

Exceptions: There's a new Content Security Policy (CSP) that can prevent loading external scripts through the use of a bookmarklet. Facebook, for example, uses this.

Note to experts:

And here's the (unminified) source, if you were curious:

(function () {
  "use strict";

  var js

  function confirmSuccess() {
    console.log("jQuery loaded!");

  js = document.createElement("script");
  js.addEventListener("load", confirmSuccess);
  js.src = "//";
